Very silent run: Intelligent glass door

These sliding doors become lightproof at the push of a button. As soon voltage is applied to the glass, the coating changes its structure and the pane becomes milky. When the polarity is changed or the voltage is drawn, the coating becomes transparent again. So privacy can be restored at any time without having to reduce the room through real walls. An E3 series E-Chain® ensures the quiet operation of this roller gate and supplies the gate with the necessary power.
